As marijuana use increases, there's increasing interest and debate over its broader health effects. One area of contention is the impact of cannabis upon cardiovascular health. In a paper published in the Annals of Internal Medicine, researchers looked at 24 observational studies that examined adults using any form of marijuana and potentially related effects on cardiovascular function and health.
Although six of the studies suggested a metabolic benefit from cannabis, the scientists concluded that all of the data was insufficient and inconclusive due to the studies' designs, limitations, scope and variation.
Poor air quality is the biggest environmental threat to public health but if you're thinking about of going to where breathing is best, you'll need a passport. A new analysis reports Switzerland has done the best job to clean up air pollution, followed by France, Denmark, Malta and Sweden.
The United States comes in 27, penalized for pollution risk factors like deforestation and greenhouse gas emission. The U.S. trailed countries like the U.K., Japan and Canada.
India and Bangladesh were at the bottom of the rankings, along with Burundi, Nepal and Democratic Republic of Congo.

This week in 1941, the first injection of penicillin into a human test subject was conducted. The patient was Albert Alexander, a 43-year-old Englishman who had scratched his face on a rose bush. The scratches turned septic, followed by blood poisoning and numerous abscesses. In great pain and desperately ill, Alexander happily agreed to the experimental antibiotic, which resulted in almost immediate improvement. But researchers had only a limited amount of penicillin and treatment was stopped. Alexander's infection returned and he died four weeks later.
Occasionally, one will hear the admonition not to drink cold beverages immediately following a meal. The act purportedly can trigger disruption of the heart, i.e. cardiac arrest, or cause cancer. In the former case, the coldness is supposed to jolt the heart adversely. In the latter, chilled liquids reputedly cause ingested fats to solidify and become persistent carcinogenic globs. There is no reputable medical literature to support either notion.
